Subject: [PATCH] ci: publish immutable date-stamped image tags
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pass build-date-tag: true to the reusable docker-build workflow so that
master builds additionally publish an immutable <docker-tag>-<YYYYMMDD>
tag, mirroring the owncloud-docker/ubuntu base image repo.
